To all whom it may concern Be it, known that I, HARRY L. EIGENBROT, a citizen of the United States, residing at" Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented new and useful Improvements in Distributer Mechanism for Typographical Machines, of which the following is a specification.

My present invention relates to improvements in machines of the linotype class, and the primary object thereof is to provide an improved construction for the distributer lift cam whereby the cam may be adjusted on the distributer screw to correctly time the operation of the distributer lift rela-- tively to the distributer screw and to compensate for wear of the cam or its cooperating roller, the cam when set being held positively, thus avoiding alteration of its adjustment and enabling a new cam to be applied readily and interchangeably to replace a worn cam.

To these and other ends, the invention consists in certain improvements, and combinations and arrangementsof parts, all as will be hereinafter more fully described, the novel features being pointed out particularly in the claim at the end of the specification.

In the accompanying drawing: Figure 1 is an elevation of a part of the distributing mechanism of a machine of the linotype class, the same being viewed from the rear and the distributer lift cam being shown in section; Figs. 2 and 3 show in side elevation and end view respectively the hub for mounting the cam; Figs. 4 and 5 show in side elevation and end view respectively the tion shown as equivalent constructions within the scope of the claim can be used.

In thepresent instance 1 designates the distributer box which has a channel through which the lines of matrices M are fed to the upper and lower distributer screws 2 and 3 as each line of matrices comes from the casting mechanism. The matrices M are fed against shoulders 4 and 5 of the top and bottom rails 6 and-7 of the distributer box. The distributer lift operates to raise the matrices successively into engagement with the threads of the distributer conveyer screws, a matrix being lifted at each revolution of said screws. The distributer lift, as shown, embodies an arm 8 which is pivoted at 9 and has a blade 10 which engages the bottoms of the matrices successively and thereby lifts them into engagement with the conveyor screws. The arm 8 is operated by a lever 11, the latter being provided with a roller 12.

13 designates the distributer lift cam. This cam is mounted on the rear upper conveyer screw 2 throu h the medium of a hub 14, the latter being xed to said screw preferably by a pin 15. The hub has a flange 16 which is provided with a circular series of apertures 17 a circular projection 18 extend ing beyond the face of the flange. The cam 13 is bored to fit upon the circular projection 18 and abut against the flange 16 of the hub. The cam is also provided with a pin 19 which, when the cam is in operative position, engages in one of the apertures 17 in the flange 16 of the hub. Suitable means is provided for retaining the cam in cooperative relation with the hub, a screw 20 being employed in the present instance which is threaded into the end of the hub and has its head seated in a counterbore 21 in the face of the cam.

In applying a distributer lift cam to the machine the hub 14 is fixed rigidly to the appropriate distributer conveyer screw 2 by the pin 15 and the cam is set in such a position on the hub as to cause the lifting of the matrices at the proper intervals to correctly engage the threads of the conveyer screws. Correct timing of the cam can be accomplished easily by inserting the pin 19 on the cam in the appropriate aperture 17 in the flange of the hub, this being done to the distributer conveyer screw this being accomplished by loosening the screw 20 and thenadvancing the cam on its hub so that the pin 19 will engage in another aperture in advance of the one previously engaged thereby. Also, when it becomes necessary to replace either the roller 12 or the cam, the cam can be readily adjusted to insure correct timing in the operation of the distributer lift equipped with the new rt. Heretofore, the cam and its hub have been formed in one piece and permanently fixed passing through the hub and screw. Rapid wear of the cam and its cooperating roller has in practice required frequent renewal of the cam owing to the incorrect timing in the lift of the matrices. It has proven diflicult to re lace worn cams ow1ng to the practical di culty of obtaining uniformity in by a pin the location of the holes in the hub of the cam and the distributer screw for the pin. These objections which existed in machmes as heretofore constructed are obviated'by the present invention, as the hub of the cam is permanently attached to the distributer screw and provision is made for setting the cam thereon whereby proper timing of the parts may be produced and maintained notwithstanding wear. a

I claim as my invention In a typographical machine provided with means for distributing matrices therein, a separator operative to lift the matrices to deliver them in proper order to the distribnter, and a cam for actuating said separator, said cam being constructed in parts adjustable to vary the point of lift and thereby secure and maintain the correct relative timing of the operation of the separator relatively to the distributer.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
